به خواندن ادامه دهیدWhat is interesting to note is that heavier than water fluids will spray less volume of fluid through a spray but the weight of the spray will still be heavier. This can be seen from the equation above as the flow rate (volume) is reduced by a 1/root SG factor where as the fluid weight of that spray will obviously be increased by a factor of SG2.
